Answer:

2

Step-by-step explanation:

The scaled factor has to be 2 because 4*2=8. You can check 2 is the correct answer by doing 8/2, which is 4. The scaled factor has to be proportional so if one side of ABC was 2 but the same side on ABC prime or A’B’C’ was 10 it would not be proportional, not a scaled factor. Because 2*10 is 5, not 8. But it does not give any other side lengths so it is 4.

Answer:

[tex]x^2-10x+16[/tex]

Step-by-step explanation:

The way I would find the equation is by finding the factored form of the equation form. That equation would be (x-2)(x-8). These are correct because if you set both of these equal to zero, your x-values will be equal to 2 and 8.

x-2=0

x=2

x-8=0

x=8

If you want the standard form of the equation,  all you have to do is multiply it out.

[tex](x-2)(x-8)\\x(x-8)-2(x-8)\\x^2-8x-2x+16\\x^2-10x+16[/tex]

Boom. There's your answer!

⅘ ≈ 0,8

(w2x - 3) ÷ 10 × z

= (-4 × 2 × 0,8) ÷ 10 × -⅘

= (-8 × 0,8) ÷ -8

= -6,4 ÷ -8

= ⅘ ≈ 0,8

Evalute (w2x - 3) ÷ 10 × z is ⅘ ≈ 0,8.

After using the linear equations method we will get 1.76.

What is linear equations?
An equation is said to be linear if the highest power of a variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the standard form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the standard form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present. A linear equation is one that has a degree of 1 as its highest value. No variable in a linear equation, then, has an exponent greater than 1. A linear equation's graph will always be a straight line.

How to calculate question by adding their values in the given equation?

firstly, the given equation is: [w2x-3]/10z

The solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).

inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.

Given inequality will be solved as below:-

( - 5 / 2 ) ( 3x - 2 ) < 6 - 2x

Multiply the other hand by 2 and solve further.

( - 5  ) ( 3x - 2 ) < 2 ( 6 - 2x )

( - 5  ) ( 3x - 2 ) < ( 12 - 4x )

Take like terms to the same side and solve.

-15x + 30 < 12 - 4x

-15x + 4x < 12 - 30

-11x < - 18

x < 18 / 11

Therefore, the solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).

Answer:

The first option

Step-by-step explanation:

The first option:

f(x) = 4(x^2)

Each time x is squared and then multiplied by 4.

___

f(1) = 4(1^2) = 4

f(2) = 4(2^2) = 16

f(3) = 4(3^2) = 36

f(4) = 4(4^2) = 64

Answer:

The first one

Step-by-step explanation:

This is because the function of it is f(x) =  4x^2. Additionally, this can be seen as there is not a perfect difference between the values.

Answer:

The x-intercept is (-2 1/7, 0).

The y-intercept is (0, -3).

Step-by-step explanation:

To find the y-intercept, substitute x with zero.

To find the x-intercept, substitute y with zero.

Finding the y-intercept by substituting x with zero:

7*0 + 5y = -15

5y = -15

y = -3

The y-intercept is (0, -3).

Finding the x-intercept by substituting y with zero:

7x + 5*0 = -15

7x = -15

x = -15/7

x = -2 1/7

The x-intercept is (-2 1/7, 0).
